The only mount you’ll ever need! This heavy-duty gooseneck mount holds your Garmin Alpha 100 or Garmin Astro 430 with your Garmin DriveTrack 70 or DriveTrack 71. This is especially useful with the Alpha as you can see your dogs on the DriveTrack and use the tone/shock feature on the Alpha. This mount can either bolt into the seat bolt or it can be directly bolted to the floor – it is very easy to install and anyone can do it in just a few minutes! This mount tightens down to keep shaking to a minimum!
